Hi. I have a jet hitting a wall before leaving the outlet located at one end of the wall. Between the impingement point and the outlet, there are some swirls. Flow is incompressible and laminar.

In this case, should one apply a more elaborate pressure discretization scheme? I used the standard scheme and the outlet pressure is off by 20% compared to expt data. When I tried PRESTO!, solution diverges.

Hi everybody,
I'm modeling a heat source in a closed room. My mesh is quite dense: 4M tetra (around the source) and 4k Hexa (far from the source).
Can anybody tell me which discretization method for pressure is better? PRESTO! o BODY FORCE WEIGHTED? What are the differences between them?
